Composite Solids

This is a pier pole found in my beach house neighborhood in Ocean City. Maryland. The pole itself is to help support the pier, along with all the other poles. The white thing at the top could be for decoration, safety, or so one knows where the pier is if they are walking on it late at night. The white thing at the top is a cone figure, which is connected to the cylindrical pole, creating the geometric idea of a composite solid. Pier poles are used to support the pier, which keeps objects and people above the water. They are also used to tie boats, crab cages, and other water-related things off of. The pier makes them (boats, cages, etc.) easy to get to, and not getting wet by the river/sea water in the process.

Regular Polygon With More Than or Equal to Five Sides

What is pictured here is an air conditioning/heat filter located in the Legard Learning Village on the Severn School campus. Creating the actual geometric shape is the protecter for the filter, letting only small particles enter the boundary, keeping large objects like humans and debris out of the filter. The shape created by the filter protector is a regular hexagon: a polygon with six congruent sides and angles. Air conditioners and heaters are used in almost every building, including trailers (called "learning cottages" by the Severn School community). In order to ensure clean air is given by the air conditioner/heater, a specific type of filter must be used to filter out the bad stuff that humans don't need, or could even be potentially dangerous. This specific filter happens to be on the outside of the building, but they may be located inside or outside of whatever building it is providing heat for.
